That's good to hear.
I just bought a set of Yamaha NX 50 speakers, that had pretty impressive bass for their size, but on some songs with deep bass they startet to distort, so they're going back.
Obviously, the A2+ will also be limited by it's size, but I'm wondering how it copes with similar deep bass frequencies?
If possible, could you check your A2's with either the start of Depeche Mode: Welcome To My World (the first song on their last album) or The Knife: Silent Shout at about medium volume, and check if you get any distortion? (What I got from the Yamaha was a slight distortion of the sub bass from the right speaker, most noticeable with my ear close to the driver.)
I'm aware that they won't go as low as a subwoofer setup, but it would be very helpful to hear how well they handle this type of low bass. Many thanks in advance!
